Aminoacyl-tRNA Synthetase

Aminoacyl-tRNA Synthetases (AARSs) are ubiquitous and evolutionarily conserved enzymes that catalyze the highly specific acylation of amino acids to cognate tRNAs. Aminoacyl-tRNA Synthetases are essential for accurate decoding of the triplet genetic code and for sustenance of all domains of life, including bacteria, archaea, and eukarya.
